So I just bought an '06 King Ranch Screw with factory basic radio. I looked behind the radio and found three plugs and found the sub plug under the backseat. I ordered a factory sub and plugged it in. I then ordered a aftermarket radio and ordered the wiring for an audio system with the sub.

I wired it all up but the metra sub plug doesn't match the third plug behind the radio. I also have a shaker 500 from a mustang and the metra plug is the same shape but the one behind my radio doesn't fit it. What does this go to? It's tied in with the other two plugs.

If i remember correctly, I had an 07 KR with premium audio. Those go to the amp.

It looks like one of the amp plugs to me too.
